Of course, the characters in the books following "Before Dishonor" think Janeway is dead, just as the TNG crew thought Picard was dead in "Tapestry." That's called dramatic irony--the characters think they're dead, but we know better. Wasn't it PAD who said that the Q never do anything without a reason? The Q messed with Picard's consciousness to teach him a lesson, and the Q must have a reason for rescuing Janeway's consciousness in "Before Dishonor"--we just haven't been let in on the secret.
